SPECIFICATION forming part of Letters Patent No. 780,176, dated January17, 1905.

Application filed May 3, 1904' Serial No. 206,153.

To (tZZ whom it may concern.-

Be it known that I, RUDOLPH HEGENER, a citizen of the United States,residing at Chicage, in the county of (look and State of Illinois, haveinvented new and useful Improvements in Wooden Columns, of which thefollowing is a specification.

This invention relates to that class of wooden columns which are builtup of a number of longitudinal segmental sections glued or otherwisefastened together, and especially to the joint between the sections,whereby they are held together.

The object of the invention is to provide an interloekingjoint ofsemidovetailed kind which will tend to prevent the sections warping orcoming apart. The sections have V- shaped interlocking tongues andgrooves which when the parts are assembled and clamped tend to draw andhold the edges of the sections together and also provide alarger surfacefor gluing than plain segmental sections.

In the accompanyingdrawings, Figure 1 is a horizontal section of thecolumn. Fig. 2 is an edge elevation of one of the sections.

Referring specifically to the drawings, it will be seen that the columnis built up of a plurality of similar staves or sections,the numher ofwhich may be as many as desired or necessary. The sections are indicatedat 6 and are segmental in general form. The faces of the edges of themeeting sections lie in radial planes; but each edge is rabbeted andundercut, so that two surfaces in different radial planes are produced,as well as an oblique surface or jog therebetween, which latter ispreferably made at about the middle line of the edge. On one edge theextended surface is next the outside, as at 7 and the rabbeted surfaceis next the inside, as at 8, the ll-shaped jog being indicated at 9. Onthe opposite edge the extended surface is next the inside and therabbeted surface next the outside, the edge of the jog being presentedin the opposite direction. In short, the opposite edges arecounterparts, so that the contacting edges of adjacent sections fittogether and interlock. The undercut is beveled to produce the V tongue,which is wedge-shaped in section and has a wedge action, assisting indrawing the staves together when clamped.

It will be seen that the locking or dovetail engagement between thesections will prevent any one section from warping or falling either inor out, and when properly glued together a strong and enduring column ispro' duced, the outside of which may be fluted or otherwise ornamented,as desired.

What I claim as new, and desire to secure by Letters Patent, is

1. A column comprising a plurality of segmental sections joinedtogether, each section having the surface of each of its meeting edgesformed in two different radial planes extending respectively from theinside and outside surfaces of the column, with a longitudinal V-shapedjog between said planes, the jog on one edge being presented toward thecen ter and on the opposite edge toward the circumference.

2. A column comprising a plurality of segmental sections joinedtogether, each section having the surface of each of its meeting edgesformed in two different radial planes extending respectively from theinside and outside surfaces of the column, with a longitudinal undercutjog between said planes, the jog on one edge being presented toward thecen ter and on the opposite edge toward the circumference.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

RUDOLPH HEG-ENER.
